False. A physical change does not create a new substance.
Atoms is the correct answer
What are the options? I can try to give you an answer if options are provided.
First, find moles of oxygen gas: (3.01 x10^23 molec.)/(6.02 x10^23) =0.5mol O2
Second, multiply moles by the standard molar volume of a gas at STP:(0.5mol)(22.4L) = 11.2L O2
